.To all whom it may concern.'

Be it known that I, HARRY W. MUNYAN, a citizen of the United States, resi-ding at Worcester, in the county of Worcester and State of Massachusetts, have invented a new and useful Battery-Connector, of whichthe VJfollowing is a specification.

This invention relates to connections for use ori-batteries, and in similar places for conducting electricity. l

The principal objects of the invention are to provide a connector of this character which will have no parts which can be bent in ordinary practice sufficiently to reduce their conductivity or to break them;. to provide such a connector with terminals of such a character that when the thumb-nuts of the battery or other terminals to which they are to be applied are screwed down into position to clamp them in place` there will be sufficient resiliency to assist in holding the thumb-nuts, and additional means for engaging the same to prevent them from becomingloosened in ordinary service, or to delay such action; and generally to improve and simplify the construction of articles of this character.

While the invention isillustrated as applied to battery cellswhich is one of its principal uses, it is to be understood that the invention isapplicable for the pur oses of connecting electrical terminals of a kinds.

Reference is to be had tothe accompanyindrawings, in whichigure l is a side elevatlon of a connector constructed in accordance with this invention. Fig. 2 is a central longitudinal sectional view of the Same; Fig. 3 is a side elee vation partly broken away showing another form in which the insulation may be applied; and Fig. 4 is a s ide elevation of a pair of cells connected by means of the form of connector shown in Fig. 3.

Most of the connectors in ordinary use are rovided with ,soldered joints which have to be bent more or less in applying and removing the connections and which under such circumstances lose their conductivity and even become broken after a short time. A connector constructed in accordance with this invention is formed in such a manner thatthis objection is obviated and so that the connections will not become loose or tools are required to connectthe device up vin batteries or l'other electrical 'appa- A-fat its ends. lThe terminals are given a spring temper so that the coils will have suf-A f icient resihency to normally bear against the binding post thumb-nuts c which hold them ositlon. This results in more firmly hol 'ng the thumb-nuts themselves in pos1- tion and preventing their `acc'zidental removal. For the purpose of assisting in this function, the wire is coiled in the direction in which the thumb-nuts are turned to tighten them and at their ends they are provided with upturned edges d. These edges may be formed in any desired way but in practice, it is sufficient to cut ofi the wire in any ordinary manner. This leaves a bur on the edge .of the wire which serves this function.

It will be noticed that the thumb-nuts areV screwed against the spring and in the direction in which the wire isV coiled and when they attempt to turn in the other direction, the bur at the Vend of the wire will have. a tendency to revent such`motion and this is assisted by t e resiliency of the coil itself.

'When the device is to be used for connecting battery cells, the two coils are turned at right-angles to each other so that they are in proper position for application to the batter; terminals as is indicated in Fig. 4, both of the connectorterminals being coiled in the proper direction.

It will be seen that the coiled terminals being iixed'in positionwith respect to the continuous conductor a, they havea certain location which results in their being readily a lied to the desired kind of terminal. T e

evice may be sup lied with any desired kind of insulation. n Figs. 1 and 2 this is shown in the form of a coating e on the wire, on the outside of which is a woven tubef held in position by two metal clips g.

In the form shown in Figs. 3 and 4, the insulation consists merely of a rubber tube h which is held in position only by the coiled terminals.

WhileI have illustrated and described a particular form in which the invention ma e embodied, I am aware that many modi cations may be made therein without departing from the spirit of the invention as expressed in the claims. Therefore, Ido not shown, but

What 1 do claim isz- 1. As an article of manufacture, a battery connector comprising a continuous conductor having resihent coiled terminals in one integral piece with the conductor, forming compressible springs at the ends thereof.

2. As an article fof manufacture, a battery connector comprising a continuous resilient p conductor havlng a resilient coiled terminal in one piece integral with the conductor, and `yhaving a sharp edge at the end thereof.

3; As an article of manufacture, a connector for electrical purposes consisting ofa continuous conductor provided at the end with a terminal comprising a plurality of convoluto -be limited to 'the particular form' l tions formed on the conductor and provided with a spring temper, said convolutions being spaced apart to constitute a coiled spring, and the outer convolution having on the end thereof a bur left by the cutting o3 of the wire and projectin outwardly, and a tube of insulating materia mounted on said conductor and extending to the terminal thereof so as to leave the terminal bare throughout the coiled portion thereof.

n testimony whereof I have hereunto set my hand, in the presence of two subscribing witnesses.
